Title: Data separation circuit
Inventor: TOEDA HIROSHI
IPC: G11B5/09
Filed: 1982-01-27
Abstract: PURPOSE:To separate PCM data correctly even if distortion takes place in input data, by making a data separation level of an input data signal coincident with a reference potential level of a data separation circuit independently of the distortion of the input data signal. CONSTITUTION:A comparator 7' compares the input data 20 with the data separation reference potential 11' mentioned later and separates the PCM data. The PCM data of a processor 8 is led to an audio output terminal 13. A data error detection circuit 81 generates a pulse signal in response to the number of errors. A counter 9 counts an output pulse of the detection circuit 81. A processor 10 detects the count output of the counter 9, operates the data separation reference potential VT where the PCM data error is minimized and outputs corresponding digital signals. A converter 11 converts the digital signal into a reference potential V of a comparator 7'. A controller 12 varies the digital quantity of the processor 10. In the constitution like this, a voltage varying means 14 obtains the reference voltage VT where the PCM data error is minimized when the separation reference voltage V is changed from V1 to VN, and transmits the voltage to the comparator 7', allowing to separate the PCM data correctly.

Abstract: PURPOSE:To improve time interval measurement resolution without increasing a clock frequency by taking out an output at a delay point divided into a prearranged number in a period of a reference clock by plural D-type FF's connected to the delay line. CONSTITUTION:A pulse of such width as to comply with a time difference between inputs A, B into input circuits 1, 2 is generated by an exclusive OR circuit 3, opening AND gate 4 and a clock from a reference clock generation circuit 5 is counted by means of a counter 8. Thus a time interval is measured. An output from the circuit 3 becomes a clock and a value 2/10 times the period To of a reference clock is detected by means of an output from a tap corresponding to 10 pieces or so of D-type FF connected to a delay line 10 held dependig on the rising of the afore- mentioned pulse. In the same way, the rising point of the afore-mentioned pulse is detected a resolution which is equivalent to 1/10 of the period To of a reference clock, so that time interval measurement resolution can be improved without increasing a clock frequency.
